"Blouse" is a song by American singer-songwriter Clairo, released through Fader Label and Republic Records on June 11, 2021, as the lead single from her sophomore studio album, Sling.

[3] Talking to Rolling Stone writer Angie Martoccio, Clairo highlighted the lyric of "Why do I tell you how I feel, when you're too busy looking down my blouse?

[3] Speaking to Gemma Sanways of The Guardian, Clairo said of Lorde's involvement that "we talked a lot about how cool it was in the Laurel Canyon era, where people would secretly do background vocals on each other's music – like Joni Mitchell with Carole King – rather than as a way to benefit the business side of things.

[7] Of the music, Moreland said that "a hushed acoustic guitar melody is soon joined by gentle orchestral flourishes courtesy of co-producer Jack Antonoff and low-key backing vocals from Lorde".

[7] The review concluded by saying that "'Blouse' is a quiet yet bold leap forward for Clairo, one that puts a spotlight on her skills as a songwriter with remarkable ease".

[8] Aside from that, Farrell also noted that "orchestral strings swell around Clairo's bruised words", and that "her vocals get slightly louder" towards the end of the song.
